Oil sampler



July 28, 1931. E. G'. FRIEDMAN OIL SAMPLER Filed June l1, 1930 ATTORNEY Patented July 28, 1931 EMERY er.` FRIEDMAN, or'nizovvlvsvinnn, TEXAS oir. SAMPLER Application filed yJ'une 11,

My invention relates yto improvements in devices for sampling oils, such as the pro-ducts of petroleum oil, and it consists in the constructions, ,combinations and arrangements herein described and claimed.

Oils which are sold by refineries are generally stored in tanks, and it is necessary often to ascertain the nature and quality of the oil at different portions of the tank. Frequently it Will happen` that one portion Will contain more sediment than another portion. The temperature of the oil in the tank Will vary With its depth, and the volume of oil in a given container Will depend t' upon the mean temperature.

An object of my invention is to provide a device by means of which a sample of the oii may be obtained from anydesired portion of the tank.

A further object is to provide a device which will not only obtain a sample of the oil, but will also give the temperature of the oil.

A further object is to provide a device of 25 thetype described which is simple in construction, but Which is positive in action, and which permits the taking of accurate samples from any desired portion of the tank.

Other objects and advantages Will appear in the following specification and the novel features of the invention Will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part yof this application, in which:

Figure 1 is a sectional view of the sampling device;

Figure 2 is a plan View;

Figure 3 is a sectional view along the line 8-8 of Fig. 1, and,

Figure 4 is an enlarged detailed view of a spring used in connection with the device.

In carrying out my invention I provide r a container consisting of an outer casing l, Which may be a cylinder of sheet metal or the like, which is closed at its bottom 2, and also at its top 3. In the bottom of this casing disiosecl a Weight 4 which may be of any suitable material such as an iron disk.

1930. serial No. 460,534.

IVithin the casing l and 'spaced there is an inner cylinder having side Walls bottom 6 and a top 7. The space bet the Wallsl and is preferably illed some heat 'insulating material 8, such asasbestos or granulated cork. l

from

5, a Ween with The inner cylinder 5 rests on the -weight 4, as shown, and communicatesby means of a tubular member 9 with" a nozzle 10 which is preferably turned toward one side.

This nozzle is provided With'aclosure 11 Which in the present instance is 'shown vas a Vflat disk hinged at'12.

` The top memberV 3 is provided with an opening, and in this openingis disposeda thermometer stem `13. This stem p a-SSeS througha guide tube 14 which is securedto the top portion 3, and lwhich extends through the portion 7 of the inner cylinder. Above the top 3 is a packing gland 15, by means of which the thermometeris held in position.` A handle 16 is endof the thermometer stem. l

provided on one A bail 17 is attached to the upper end of the casing and to this'. bail is secured a plate 17. lOne end of a spiral spring 18 is attached to the plate 17 vand the other end. is attached to a plate 19, as shown "in Fig. 4. A U-shaped link 20 is secured to thel plate 17 While a similar U-shaped link' 21' is secured to the plate' 19 at' right angles tothe link 20, the ends of' these links being spaced apartso asto provide for' the stretching of the spring 18. At-22 I have shown a cord or cable which is attached tothe upper eye of a member 23. This Ymember 23 passes through-the plate 19 and Vhas 'a lower eye to which a cord 24v is secured, the other end of the cord being attachedto the closure 11. y -From the foregoing description of an eyeV 25 vof n the various parts the operation thereof may be readily understood. When it is desired to take asample of the oil let us say from the extreme bottom of the tank, the valve or closure 11 is shut and the container with the thermometer in place is lowered into the tank through theoil, and due to lthe Weight 4 it is carredfto the bottom. Darin movement from the top to the' bottom g itsit is suspended from the spring 18. Now when the bottom is reached a quick pull or jerk on the cord 22 Will cause the opening of the closure ll by bringing it from the full line position shown in Fig. l to the dotted line position. The links 2O and 2l are for the purpose of providing means for raising the containerink the event that the spring 18 should break. These links, however, do not interfere with the normal action of opening the closure, as stated.

The oil Will now enter through the nozzle 10 and pass on into the container, the air passing out through the Anozzle l0V which is of suiiicient size to permit this action. The container which is now filled With the oilfisleft in position until the thermometer has registered the proper temperature, and then thesampler is pulledrapidly to the top Where the temperature oitv the oil may `be read by removing thev thermometer from the container. The V.oil'then may be tested for any-sediment -or extraneous matter that is contained therein.

f In takingga'sampleyfromthe central portionfofthe tank,'the container is merely loweredv to the central portion, and the closure is then opened in th'efmanner already described. The" sampler may bey lowered vto any other depthv and samples may be taken in the manner described.

Y Itis possible to-get a mean temperature of the-oil by lowering it' and vraising it with the -valve or closure 11 open, since theoil Will begin/to flow in-as soon as the container is submerged randy will continue to loW in until' it hasiilled the container. By calculating the time that theA container will be Ville'd, the movement down and up may be gauged so as to substantially lill the container at the top of 'the upwardv movement. The temperature ofthe oil and also the chara'cter Willbe afmean or averageltemper'- atu're or character ofthe oil in the tank.
